LO5- The nerve system

Dendrites

branched projections of a neuron that receive signals from other neurons.

Axons

long, slender projections of a neuron that transmit electrical impulses away from the neuron's cell body to other neurons or muscles

Synapse

the space where one neuron sends signals to another neuron.

Sensory nerve

carries signals from external stimuli to the central nervous system (CNS).

Relay nerve

transmits signals between sensory nerves and motor nerves within the central nervous system.

Motor nerve

carries signals from the central nervous system (CNS) to muscles and glands, initiating movement or secretions.

Cause of multiple sclerosis

an autoimmune disorder where the immune system mistakenly attacks the protective covering (myelin) of nerves in the central nervous system, leading to inflammation and damage

4 symptoms of multiple sclerosis

Fatigue, bladder issues, muscle spasms, numbness and tingling

4 Risk factors of Multiple Sclerosis

Genetics, lack of vitamin D, smoking and viral infections

3 ways to monitor and diagnose MS

MRI Scans, evoked potential test and lumbar puncture

3 ways to treat MS

corticosteroids for inflammation

disease-modifying therapies (DMTs) to alter the course of the disease

symptom management medications for symptoms like muscle spasms, pain, and fatigue

4 Care needs for MS

Physiotherapy, speech and language therapy, home adaptations and occupational therapy
